Internet technology as the cutting-edge of the current information technology, it has penetrated into every aspect of human life, more and more government agencies, enterprises are using Internet to improve their office efficiency and to establish new business operation model, in order to improve its reaction ability in fierce competition. Internet has brought convenience for people to work, while the security problem of network also will follow. The internal network not only needs to ensure the security of their data, but also needs to exchange data with the external network, then by adopting network security isolation system which takes gatekeeper technology as its core technology, so that we can ensure that internal network and external network will have physical isolation at any time, meanwhile, according to business needs, it also has multiple forms of information and data’s exchanges.

Online homework correcting system based on ASP.NET is an online homework correcting system based on B/S mode, which can provide online work service for teachers and students to improve school teaching level. The characteristics of the system are making the traditional pattern of homework assignments and correcting networked, strengthening the connection between teacher and student, and also improving the teaching efficiency. How to use ASP.NET technology to build an online job submission and the process of correcting system, this article discusses the concept and characteristics of B/S mode, the superiority of ASP.NET and the analysis of general homework system. The system mainly completes the homework uploading and the teacher corrects for homework, it has high stability and simple operation.

The arrival of information age means the change of teaching and learning methods, with the development of computer technology, multimedia technology and network technology, the teaching mode of interaction through the network are also popular to carry out gradually. Changes have taken place in teaching methods, teaching means, teaching form and teaching idea through the application of computer in teaching. Distance education, online examination system, the development of online learning system and online homework system greatly promote the development of the educational business and also bring a huge change to modern education, profoundly affected the modern teaching domain. Applied-information technology plays an increasingly important role in contemporary teaching. To study the application of applied-information technology in teaching research has important theoretical and practical significance.At the same time of computer aided teaching, the arrangement and correcting homework are particularly important for checking the teaching achievements and the degree of students what have mastered.

With the rapid development of network technology, computer networks and the Internet have become an important force in promoting social development, many enterprises and government agencies have been or are preparing to build its own internal network as the center of the entire information system, through a variety of methods accessed internal network to the Internet, thereby greatly enhanced their information acquisition and processing capabilities. Isolated net gap is an enterprise-level physical isolation technology; its generation is to solve the problems that exist in network security.

The article studies on the application of the shuffled frog leaping algorithm (SFLA) in power distribution network reconfiguration, taking the minimum loss and voltage quality of distribution network as a multi-objective function. The article improves the initial solution generation strategy of traditional genetic algorithm, which ensures the initial solution is feasible solution. Shuffled frog leaping algorithm and genetic algorithms are combined and proposed as shuffled frog leaping genetic algorithm (SFLGA). The algorithm uses the efficient coding strategy based on the basic loop and initial solution generation strategy, improves the calculation efficiency. The algorithm is verified by simulation results from test case on IEEE 33-bus system with distributed generations.
